Scenario One

A parent wants to explore the types of exposure. The select a particular exposure (e.g., TV) might impact their child. They search for the exposure and are given an overview of the known outcome categories. Visualise info about the uncertainty for each effect. They filter the results for their child’s age. They click into an outcome category to get more information on the result (e.g., text summary, info about reason for the uncertainty).

Task One

Explore the exposures that there are evidence for.

Not really sure how to do this one. I guess one option is a bar chart of the exposures by the number of outcomes associated (and vice-versa).

Idea One

Notes

Task Two

Explore an overview of the outcome categories for the selected exposure category.

(E.g., if they have chosen ‘video games’)

Idea One

Using length as the main idiom.

Notes

Idea Two

Using position as the main idiom.

Notes

Task Three

Visualise the uncertainty for the selected exposure.

(Not sure how to do this one)

Task Four

Filter the results by child’s age

Idea one

This is just the same as Task Two. E.g.,:

Task Five

Click into an otcome category to get additional information on the result.

(Can’t really do this is ggplot)

Scenario Two

A domain expert wants to explore evidence for screen time in more detail. Use the system to get an overview of the evidence (exposure, outcome, effect size). They search for the exposure and/or the outcome, and optionally filter by age. They click into a relationship and can access the forest plot of the original studies, and the link to the original meta-analysis (and other, related studies, uncertainty). Three levels: evidence, uncertainty, meta-data.
